I have to say that I am a believer in @DnKFab’s frigerated air dryer.
Here is my not as inexpensive as his but patterned off his idea. I’ve got $175 in this setup with an $85 fridge, $60 in 40’ of 1/2" copper tubing, and the rest in fittings, and the two house water filter housings for the desiccant.
Compared to no cooler water collection at my plasma, initial trials with the fridge and final setup, wow.
I would get 2 tablespoons of water at my plasma water sep (about half as much in the water sep mounted on the air tank) after about 1 hour of actual cut time, then near zero with the initial setup, unless I did a stupid and used the same airline as a blow gun feed, now I have a drip leg after the fridge and before the desiccant traps. Initial blow out of lines put some water in the first desiccant and before I put the drip leg in trap, nothing since.
